Vedclass · Answer

(A) The water molecule $(H_2O)$ is a polar molecule,meaning it has a permanent electric dipole moment.When a charged rod (whether positively or negatively charged) is brought near a neutral stream of water,it induces a redistribution of charge within the water molecules due to electrostatic induction.Because the water molecules are polar,the end of the molecule with the opposite charge to the rod is attracted,while the end with the same charge is repelled.Since the attracted end is closer to the rod than the repelled end,the net force is always attractive.Therefore,the water stream will bend towards the rod regardless of whether the rod is positively or negatively charged.

$A$ girl brings a positively charged rod near a thin neutral stream of water from a tap. She observes that the water stream bends towards her. Instead,if she were to bring a negatively charged rod near to the stream,it will
